ADTRAN-ERPS-MIB · .1.3.6.1.4.1.664.5.79.1.1.3.1.3

Object

column r/w Enumeration

The protection mode requested by management for the local 
station that can affect the protection status of the ERPS
station, according to the set of rules describing the ERPS 
protection.
              
When read, this object returns the last command written 
unless it has been preempted, or idle if no command has been 
written to this interface span since initialization.
              
              
There is no pending of commands, that is if a command has 
been preempted by a failure, when the failure clears the 
command is not executed.
              
If the command cannot be executed because an equal or \
higher priority request is in effect, an error is returned.
              
writing idle to a span that has no pending protection
command, has no affect. An idle clears an active WTR state.
              
The protection commands (arranged in ascending priority 
order) are:
              
idle
This command clears the protection for the specified 
interface span.
This value should be returned by a read request when no 
protection command has been written to the object.
              
manualSwitch
A protection command on each end of a specified span. This 
command doesn't have precedence over automatic protection, 
and therefore it can't preempt
an existing automatic protection request.
              
forcedSwitch
A command on each end of a specified span. This command has
precedence over automatic protection, and therefore it can 
preempt an existing automatic protection request.
              
Default value of protection command is idle.
